I installed Fedora 10 on my Macbook last night/this morning. Here's my experience so far:
The Fedora installer (Anaconda) sucks at partitioning. Really badly. It couldn't handle the Mac HFS+ partitions, so I had to first use Ubuntu to get a partition Anaconda could handle. So I told Anaconda to resize Ubuntu's ext4 partition and install to the free space. (Incidentally, Anaconda did not give me the option to format to ext4, even though Fedora 10 supposedly allows this option). It appears that Anaconda's partitioner corrupted the filesystem on Ubuntu's partition, because it no longer shows up in my boot menu and Fedora can't mount that partition. Which means that after an entire day of installing Ubuntu and all my apps for it and tweaking it just the way I like it, it's gone. I'm hoping that I'm wrong and Fedora just overwrote my bootloader, but it looks like I might have a reinstall in my future.
Aside from that, Fedora is fairly nice. It has a good, clean implementation of GNOME with a much sexier default theme than Ubuntu's. It seems pretty fast, and has low memory usage. The package management options provided in Anaconda were excellent. My trackpad mostly works out of the box, though I currently lack right-click options. I haven't done much configuration yet, so I'm sure a solution to this will be found soon. The desktop effects enabled as options in the default install are good- not overdone like my typical Compiz setup, but understated and classy. I have wobbly windows and a desktop cube, so I can live without windows bursting into flames.
I was expecting installation of my Broadcom wifi driver to be filled with ndiswrapper fun and a painful process, since the Fedora release notes makes clear their strong stance against proprietary drivers and even against ndiswrapper. However, it turned out just to be a matter of enabling a non-free repository and yum-ing the driver. Slightly more work than Ubuntu's pop-up "Do you want to use non-free drivers?" but still much easier than my first experience with Linux wifi.
So, it's mostly an out-of-the-box experience, and it's pretty decent overall. The add/remove feature is intuitive, although the repos are not as extensive as I'm used after coming from Debian-style distros. Seems to be a very solid distro and I'm looking forward to seeing more of what it has to offer.
